I downloaded the "Arch Linux" duktoR6 package from https://pkgs.org/download/dukto "Arch Linux", the actual download is http://archlinuxgr.tiven.org/archlinux/ ... pkg.tar.xz.
And converted the contents into a Puppy compatible ".sfs" file, 'dukto64-R6.sfs', which can be downloaded from https://www.mediafire.com/folder/a67qk7e479dxa/dukto.
Since this dukto needs qt4, I downloaded 01micko's 'qt4-4.8.7_slacko64-7.0.sfs' from http://distro.ibiblio.org/puppylinux/pe ... acko6415.0, the actual download is https://distro.ibiblio.org/puppylinux/p ... 64-7.0.sfs.
To install Dukto-R6, load both these ".sfs" files with "sfs_load".
Although the qt4 ".sfs" is intended for slacko 7.0, it also seems to work in ScPup64.
But then ScPup64 is a Slackware based Puppy too.
Enjoy.
